The Day Sky
Look up at the sky. What does it look like now?
The day sky and night sky are different. The sky is bright in the day. The Sun is a big ball of hot gas. It makes the day sky bright.
Sometimes you can see the Moon in the day sky. Most of the time you can see the Moon at night.
The Sun is bigger than Earth. The Sun looks small to us. It is far away.
Earth gets light from the Sun. Earth gets heat from the Sun too.
The Sun seems to move in the sky. This is because Earth is moving. Where is the Sun in the sky over you now?
Day and Night
Earth turns around and around. This is its rotation.
One rotation takes Earth one day. We do not feel Earth moving. But it turns very fast!
